Strategy is a choice, so you might as well choose to win. For circularity leaders, the framework offers an opportunity and a moment of truth.

The Logic of Scientific Revolutions

Two esteemed points of view on the nature of progress, how it applies to strategy, and what it means for circularity transformation.

Industrial Dynamics

The summer reading series arrives at the wellspring: Jay Wright Forrester's 1961 book, the bedrock beneath circularity's systems thinking.

Circular Century

Coping with Abundance

Every age of plenty before this one was fleeting — squandered by an economy that profits from more. The Circular Century is the first abundance built to stay. Which leaves only the question of how to cope with it.
